This invention relates to a new article. of manufacture for use as an insectifuge, and in particular, for warding ofi" attacks of mosquitos.

The usual preparations for driving. away mosquitos comprise odoriferous essential oils or oily pastes which are often of a greasy nature or contain a non-volatilethickening material of an offensive character.

My invention, as a new article of manufacture, consists in a roll or tape of absorbent material such as paper, cloth, etc.-, carrying in its fibers an impregnating or saturating amount of an essential oil of a character adapted to ward off the approach of mosquitos or other insects.

In preparing my improved article of manufacture, I preferably take tissue paper of the type known as crepe or crmkly, cutting this into narrow strips of about threeeighths to one-half inch in width, and from. say three to six yards in length. This is rolled into a firm coil of about one and one half or two inches in diameter. The coil is then impregnated with suitable essential oil material. For this purpose I find a mixture consisting of twenty-one parts of oil of lemon grass, seventeen parts of oil of cedar leaf, twenty parts of heavy oil of camphor, and seven parts oil of wintergreen leaves to be satisfactory. If it bedesired to have the oil fixed to a greater extent in the fibers of the paper, I make use of such thickening material, for example, as soap, a suitable formula consisting of oil of lemon grass, seven parts; oil of mace, one part; oil of Wintergreen leaves, one part; oil of cedar leaf, four parts, and oil of camphor, three parts, diluted with an equal volume of alcohol and carrying a saturating quantity of soap. To effect solution of the soap, I ordinarily take well dried and finely pulverized sodium or potassium soap, such'as stearate or palmitate, and heat the soap with the essential oil and alcohol mixture until the solution becomes saturated with the soap. Thissolution is allowed to settle and the clear portion decanted from any sediment, and while still hot and fluid, is readilyabsorbed by the paper coil. On cooling, the composition sets in the fibers of the paper to form a firm mass. In'this way, the paper coil is freed from superficially adhering fluid oils, so that the hands or clothing are not soiled by contact therewith. A mixture of concentrated sulfated or sulfonated oil-or soluble oil, as it is commercially known, with dry soap is an excellent thickener. 7

By reference to the accompanying drawing, the manner in which my invention is carried out may be clearly seen.

In the drawing, Figure 1 depicts a body strip or portion as a coil of crinkly tissue paper impregnated as hereinbefore described, while Fig. 2 shows the coil as packaged for shipment.

- In the'drawings, 1 indicates the coil made up of the tape 2 carrying a saturating thickener, the alcohol may be omitted by proceeding as follows :-Twenty parts of the he paper tape is preferably fastened essential oil -mixture are heated with one part each of anhydrous sodium stearate and potassium oleate and two parts sodium sulforicinoleate until solution is effected. The paper is then impregnated with this mixture while the latter is hot and fluid.

Instead of embodying in the form of a coil, the absorbent tape may of course, be. variously shaped into other forms suitable for carrying out the purposes of this invention.

Inusing this new article of manufacture in the coil form, a strip of say five or six inches may be torn off when desired and may be hung at thepoint where it is desiredto drive away the mosquitos, the odors of the essential oils arising from the paper vicinity. By the use of the crinkly paper, a very large evaporating surface 1s secured from a comparatively short strip of the A 'tape, so that even by the use of a very short paper tape em loyed in the bodiment, the evlce is one 0 great utility.
